APOD: A Sun Pillar over Norway (2018 Jun 06)

Image A Sun Pillar over Norway

Explanation: Have you ever seen a sun pillar? When the air is cold and the Sun is rising or setting, falling ice crystals can reflect sunlight and create an unusual column of light. Ice sometimes forms flat, six-sided shaped crystals as it falls from high-level clouds. Air resistance causes these crystals to lie nearly flat much of the time as they flutter to the ground. Sunlight reflects off crystals that are properly aligned, creating the sun-sun-pillar effect. In the featured picture taken last week, a sun-pillar reflects light from a Sun setting over Fensfjorden, Norway.

Must be a metaphor because no fire is involved. Fire is a chemical reaction. This is an optical reaction of light and ice.

Maybe it got fixed, thanks to your post. At least a nice, funny image comes up for me now.

And the first link: sun pillar going to www.atoptics.co.uk ... that is fantastic. Such a treasure-trove of atmospheric effects I have never seen.
